The Witch Bolt spell is missing for sorcerers.
See Players Handbook Page 289
I'm not seeing the witch bolt listed anywhere in my lite PDF let, what chapter is it in?
Players Handbook Page 289 (Part 3: Spells):
Level 1 Spell for Wizard, Warlock, and Sorcerer
Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a twig from a tree that has been struck by lightning)
Duration: Concentration, up to 1 minute
A beam of crackling, blue energy lances out toward a creature within range, forming a sustained are of lightning between you and the target. Make a ranged spell attack against that creature. On a hit, the target takes 1d12 lightning damage, and on each of your tums for the duration, you can use your action to deal 1d12 lightning damage to the target automatically. The spell ends if you use your action to do anything else. The spell also ends if the target is ever outside the spell's range or if it has total cover from you.
At Higher Levels:
When you cast this spell using a spell slot of 2nd level or higher, the initial damage increases by 1d12 for each slot level above 1st.
